West builds collections using invented systems, often relating to a certain colour. In the Trolley series of photographs West has experimented with building collections of block colour in the supermarket, a place where colour is in abundance, in order to understand how colour may look in mass.

In this work the subject matter of shopping and consumerism is a framework in which to act out abstract concepts of aesthesia and control with a collection of coloured objects. Being located in a trolley, this canvas inevitably references consumer society and disposable culture.
